Cooling Fan Module LED
The subsystem has a novel approach to stabilizing the temperature within the subsystem:
When the sensors within the enclosure detect critical working conditions, such as high ambi-
ent temperature or the failure of any cooling or PSU module, the system will turn the cooling
fans to high speed to extract more heat. Once the ambient temperature cools down to normal
or the faulty module has been replaced, the cooling fans return to normal speed.
